Abstract:

This paper reflects the current state of

ichthyofauna in the research made in Bistrita

River Basin, regarding the inventory of the fish

species that inhabit the rivers Calu and Iapa, right

tributaries of the river Bistrita. The data obtained

by us were compared with those existing in the

literature (Bănărescu P., 1964) to capture changes

recorded in the structure of the fish communities

after the human impact appeared during 1960 and

up to present. So, there were made investigations

regarding the composition in the species, the

fisheries of these rivers through the calculation of

the ecological index, and the determination of the

index of biologic integrity (IBI), which reflects

best the actual state of the fish population from

these ecosystems.

Keywords:

ichtyofauna, stock, biodiversity, integrity index, Bistrita basin.
